No, they are not relatively prime.
Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are relatively prime...
No. To be relatively prime, the only common factor they could have would be the number 1. They also have 5 as a common factor, so they are not relatively prime.
The greatest common factor of 52 and 65 is 13
80% (52/65)*100 = 80
No, 50 and 65 are not relatively prime.

No.
Yes, they are relatively prime.
Yes, they are relatively prime.
Yes, 25 and 65 are relatively prime because their greatest common divisor (GCD) is 1. The prime factorization of 25 is (5^2), and for 65, it is (5 \times 13). Since they share a common factor of 5, they are not relatively prime.
52
Yes.
